Gamma-Ray Radiation Effect on Two Species of Canavalia Performance

Abstract

Abstract In Indonesia, sword beans are still only occasionally grown since the superior variety is not readily available. An alternative breeding technique to enhance plant characteristics is mutation. The goal of this study was to determine how gamma radiation affected the growth and performance of the two Canavalia species. Four accessions of two Canavalia species each received one of five gamma-ray treatments (0, 50, 100, 150, and 200 Gy). Plant morphology during the germination phase, growth type, plant capacity to produce flowers and pods, flowering age, maturity age, seed weight per plant, seed weight per plot, and seed weight per hundred seeds were all observational factors. Using a factorial randomized complete block design, the data were examined. Microsoft Excel was used for the descriptive analysis, whereas STAR software was used for the analysis of variance and further analyses. Gamma-ray doses of up to 200 Gy have not been successful in altering the characteristics or reaching the LD50 in sword bean. The weight of the seeds per plant and per hundred seeds varied significantly, but the dose and accession variables were inconsistent, making it impossible to determine the ideal combination of the two parameters at this time.
